Perhaps you should try some spelling variations:
основііе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіііе\\" (Expand Search), основеііе\\" (Expand Search)
основііеіеіііе\\" » основііеіііе\\" (Expand Search), основеіеіііе\\" (Expand Search), основнііеіііе\\" (Expand Search), основіііеіеіііе\\" (Expand Search), основеііеіеіііе\\" (Expand Search)
основеіе\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіеіе\" (Expand Search), основееіе\" (Expand Search)
основ\\" » основі\\" (Expand Search), основе\\" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((\\\"ґрунтова ((основііе\\\" OR основеіе\\") OR основііеіеіііе\\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основііе\ OR основеіе ) OR основііеіеіііе\ )) OR (\ ґрунтова основ\ ))~.
